mode for a PD that does not perform Layer 2 classification, or if the switch
performs 2-event Layer 1 classification.
•
802.3at: The port is powered in the IEEE 802.3at mode and is backward
compatible with IEEE 802.3af. In this mode, if the switch detects that the
attached PD requests more power than IEEE 802.3af, but is not an IEEE 802.3at
Class 4 device, the PD does not receive power from the port.
c.
Power Limit (W): Manually set a value from 3.0W to 30.0W, with step increments
of 0.2W.
Power limit can be set only when the Power Limit Type option is set to User.
The default is 30.0W.
d.
Port Priority: Select the priority for the port in relation to other ports if the total
power that the switch is capable of delivering exceeds the total power budget.
•
Low: Low priority. This is the default setting.
•
High: High priority.
•
Critical: Critical priority.
e. Power Limit Type.
•
None: No power limit is applied.
•
Class: The power limit automatically adjusts based on the class of PD.
•
User: When this setting is selected, you can manually set the Power Limit (W).
This is the default setting.
f.
Detection Type.
•
Legacy: The port performs legacy detection.
•
IEEE802: The port performs a 4-point resistive detection. This is the default
setting.
•
4pt 802.3af + Legacy: The port performs a 4-point resistive detection, and
if required, continues with legacy detection.
